This Double-Roller Timing-Chain set is a perfect complement to our high-performance camshafts and other LS1/LS6 engine components. It offers greatly enhanced strength and accuracy compared with the stock piece, and even allows for timing adjustments (advance or retard) of up to 8 degrees.

The set contains an adjustable, nine-keyway nitrated crankshaft sprocket, a double-row chain, a nitrated camshaft sprocket, two oil-pump-spacer plates, detailed instructions, and all necessary installation hardware.
